Abstract
The invention discloses a freeze-drying processing method of whitebaits, which mainly comprises choosing, cleaning, water logging, quick freezing, dewatering and drying, refining the dried material and storing in the environment of 0-10 deg. C. The processed ice fish can be stored for a long period of time, and its natural state can be retained.
Description
Technical field
The present invention relates to the processing method of a kind of silverfish, particularly a kind of employing freeze drying technology carries out method for processing to silverfish.
Background technology
Silverfish belongs to salmon shape order, smelt suborder, Salangidae.Its entire body does not have squama, and is transparent, no os osseum thorn, and fine and tender taste, the equal edible of whole fish body, high protein, low fat, nutritious, delicious flavour.Traditional processing method is generally pickles or makes the dried fish preservation, and these processing methods have certain influence to the aspects such as form, nutriment, size, quality, color and luster and local flavor of silverfish.
Summary of the invention
The purpose of this invention is to provide a kind of instant edible, can preserve the long period again, and keep the native state of silverfish, to the freeze-drying processing method of the little silverfish of aspects such as form, nutriment, size, quality, color and luster and the local flavor influence of silverfish.
The object of the present invention is achieved like this: the freeze-drying processing method of a kind of silverfish, the silverfish of fishing for is cleaned with fish washer, and with the silverfish after cleaning, clean water temperature at 10-15 ℃, cleaned the back draining 5-15 minute; Silverfish is discharged in the dish after the sterilization; Silverfish behind row's dish carries out quick-frozen, and temperature drops to below-20 ℃, and freeze-off time is no less than 6 hours; Silverfish after quick-frozen is good is inserted in the freeze-drying storehouse of vacuum freeze, and between the vacuum 30-150pa, condenser temperature is below-18 ℃ in the control storehouse, and the radiant panel temperature makes material dehydrate 0 ℃ of following temperature between 60-120 ℃; With dehydrated and dried material at temperature 12-22 ℃, carry out selected classification in the aseptic toilet of humidity＜40% after, place 0-20 ℃ environment lucifuge to deposit.
Among the present invention with quick-frozen the silverfish after good insert in the freeze-drying storehouse of vacuum freeze, between the vacuum 60-120pa, condenser temperature is below-18 ℃ in the control storehouse, the radiant panel temperature makes material dehydrate 0 ℃ of following temperature between 80-100 ℃;
The freeze-drying processing method of silverfish provided by the present invention, with select, clean, after silverfish adopt the method for quick-frozen and vacuum refrigeration to process, aspects such as form, nutriment, size, quality, color and luster and local flavor influence to silverfish is little, silverfish can preserve the long period, and keeps its native state.
